Resolvin D2 Relieving Radicular Pain is Associated with Regulation of Inflammatory Mediators, Akt/GSK-3β Signal Pathway and GPR18.
Neuroinflammation induced by protruded nucleus pulposus (NP) has been shown to play a significant role in facilitation of radicular pain. Resolvin D2 (RvD2), a novel member of resolvin family, exhibits potent anti-inflammatory, pro-resolving and antinociceptive effects. But the effect of RvD2 in radicular pain remains unknown. ⋯ Furthermore, immunofluorescence showed that GPR18 colocalized with neurons and astrocytes in spinal cord. The results suggested that RvD2 might attenuate mechanical allodynia via regulating the expressions of inflammatory mediators and activation of Akt/GSK-3β signal pathway. RvD2 might offer a hopeful method for radicular pain therapy.
